What is 6 more than 5 times a number (x) is at least 21

Six more than five times a number is at least twenty one is set up like this:

6 + 5x ≥ 21

By subtracting six from both sides you're left with 5x ≥ 15

Divide five from both sides to isolate the variable and you're done.

x ≥ 3 (By being greater or equal to three x can be 3, 4, 5, 6, etc.)

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
